Question

(1 point) Consider the following small data set.

Find the linear correlation coefficient.

Answer 1

Answer #1

Solution ;-

XY X^2 Y 28 100 196 х 10 14 7 14 16 19 30 280 266 210 420 Y^2 784 361 900 900 676 49 30 26 196 256 n sum(XY) sum(x) sum(Y) su

The linear correlation Coefficient is given by the formula,

( 3 )-( ^3)* (x3)-(3) ... (43)(x3) - 3 )

By substituting all values in it, we get,

r = - 0.4617
